Whatever may be the difficulty of determining the essential characters of#P . major, media, and minor, there is
none with respect to the present species. It is a beautiful little plant, and one of very great rarity. It was long supposed
to be peculiar to a wood belonging to Brodie House near Forres, where it was found by Mr. Brodie himself,
as well as by Mr. Hoy of Gordon Castle. That wood has been destroyed, and together with it the little fragrant
Pyma. In 1824, however, it was discovered plentifully in the woods at Scoone*, by Mr. Bishop; and from specimens
there gathered, our figures have been made. It is abundant in Switzerland and Germany, and in the subarctic
regions of North America, where it has been gathered by Dr. Richardson.
